Xinyu Wang vs Daria Kasatkina — R128 — Canadian Open

Break-point efficiency decided it. Daria Kasatkina converted 7 of 11 chances while Xinyu Wang went 8 of 17, the gap that let Kasatkina win a Canadian Open opener in which Wang took more points, 104 to 98. Wang won 73 percent of first-serve points in a three-break opening set; Kasatkina's answer was 4 for 4 on break chances in a seven-break second set she stole in the tiebreak. The third nearly slipped away. Wang broke for 5-3 in game 8, but Kasatkina claimed the last four games, breaking in game 9 and in game 11 for 6-5 before serving it out 2 hours, 23 minutes in. It is her first win since Wimbledon's first week and trims a series Wang had led 2-1 on record.
